^ as i see it, that actually wouldnt be correct. how much "horsepower" you in affect gain from removing weight, is a linear process. say, 10lbs of weight lost equals gaining the feeling of having one more horse power, this would be true for all cars.

if you do it the way you have suggested, it would vary from car to car.

im still searching the net for the actual true numbers, but from what ive read so far, about 10lbs lost, gives you the feeling of one more horsepower.

thanks

Let's see, if I lost 120 lbs I would feel like the car gained 100 hp - not that I believe it...

 

Math FTW!

 

It *IS* different for different cars. Which do you think would benefit more from losing 10 lb, a 420hp 4000 lb. Camaro SS or a 80hp 750 lb. Formula 500? The Camaro won't even notice the difference, but the formula car would be measurably quicker.

If you can't see reality when it is presented to you, your search for the "actual true numbers" is in vain!

 

Believe it and it could be some damn good motivation... but rethink your math.. 10/12lbs = 1hp.. if you lose 120lbs thats around 12hp

 

Like ZDan mentioned it is different for different cars, but you can go further and say that it is continuously changing even for the same car.

For example a 300hp 3000lb car will need to lose 10lb to "gain" 1HP. Now you are at 2990lb and need to lose about 9.97lb to "gain" another 1HP. If you keep on going in 10lb intervals you find that you need to lose 98.5 (rather than an even 100lb) to "gain" 10HP.

Even the 98.5lb for 10hp is still off because we went in intervals of 10lb. The number becomes more accurate as the interval becomes smaller until you eventually get infinitely small intervals (the idea behind integrating). It would be cool if someone actually came up with a mathematical expression for this.

 

And to complicate matters, not all weight is equal. When it comes to acceleration, 1 lb off a rotating mass like a wheel, driveshaft, or flywheel is worth more in acceleration than static locations.

 

Good point and you could even stretch it to any "unsprung" weight, correct?

 

It would be almost impossible to test the theory anyways, reducing weight wont show up on the dyno, and if you have two s2ks weighing in at 2600lbs (same weight reduction mods) both with 240hp they will never consistently run the same time down the track. Its a known fact that reducing weight will make your car faster, but thats about it.
